Micro Manipulator

This is an easy to print manipulator.
It uses only about 1 meter of material.
It is small and will break easily if overworked, so it is of no use to you, but it works like a machine.

After printing is finished, gently twist the lever or rod part or use a cutter to remove the adhesion.
If the adhesions are properly removed, you can push and pull the ring to open and close the gripping part slightly.

The loop spring part can be easily broken if strong force is applied. On the other hand, if you apply only weak force, the spring will remain stiff for a long time. If you bend it moderately and deform it plastically, it will continue to work well for a while.

There are two types of data. The one with the file name "manipulator" closes the gripping part when the ring is pushed in, and the one with the file name "reverse operation" closes the gripping part when the ring is pulled.

I made this as a challenge to design the mechanism that is established by bending the material as
